The spatial extent (area) of each state is expressed in approximate km2 (column 3), and as a percentage of the total area of the CFR (in parentheses). Spatial overlaps with states of the two climatic variables are also indicated (columns 4 and 5). Column 5 indicates the resolution of the GIS layers used, along with sources (in parentheses).
